Bonuses

If your item includes item bonuses, check the table below for the minimum item levels the game's math expects permanent bonuses to be applied to. A lower-level item might give such a bonus temporarily, but keep track to make sure the item isn't effectively permanent. If a character typically Hacks three or fewer computers a day, there's no difference between a +2 item bonus to Hack a computer and an activation that gives a +2 item bonus to Hack three times per day.

For attack bonuses, AC, and saves, the minimums match tactical- and higher-grade weapons and armor. Skill bonuses come on a wider range of items. Some are more broadly useful, so an Athletics item might be more expensive than an equivalent Piloting item. Gaining a bonus to Perception is especially valuable compared to gaining a bonus to a skill. Just because an item is the minimum level for its bonus doesn't mean the bonus should be the item's only power. The item can and should have an additional interesting power beyond the bonus. Likewise, an item can come at a higher level than the minimum, but if it's much higher, its abilities start to compete with the next bonus.
